With ad-hoc meetings, people can be overly cautious: "maybe this is not that important", "maybe my manager is busy". With periodic 1:1s, the manager has already allocated time to listen to you, so it's easier to talk about what's going on: sometimes it's important stuff, others not that much, but there's communication. However, it can get bad if people wait for the 1:1s to address important which should be taken care of before.
